Abstract: An antenna apparatus includes a ground plate, a radiator, and a signal source. The radiator is disposed on the ground plate. The signal source is configured to feed an electromagnetic wave signal of a first frequency band into the radiator. A first slot and a second slot are disposed on the ground plate. Both slots are closed slots and surround the radiator, and are used to restrain current distribution on the ground plate.
